Michal Meloun 68225a196f Simplify startup of secondary cores and store MPIDR register to pcpu.
- record MPIDR for all started cores in pcpu, they will be used as link
   between physical locality of given core, ID in external description
   (FDT or ACPI) and cupid.
 - because of above, cpuid can (and should) be freely assigned, only boot
   CPU  must have cpuid 0. Simplify startup code according this.

Please note that pure cpuid is not sufficient instrument to hold any
information about core or cluster topology, nor to determistically iterate
over subpart of cores in CPU (iterate over all cores in single cluster for
example). Situation is more complicated by fact that PSCI can reject start
of core without reporting error (because power budget for example), or by
fact that is possible that we booted on non-first core in cluster (thus with
cpuid 0 assigned to random core).

Given cores topology should be exhibited to other parts of system
(for example to scheduler for big.little or multicluster systems) by using
smp_topo interface.

FreeBSD Source:

This is the top level of the FreeBSD source directory. This file was last revised on: FreeBSD

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
